Abstract

The main purpose in this study is to attempt to improve the operational performance of highly congested urban arterial intersections by using Unconventional Arterial Intersection Designs (UAIDs) as a solution of congestion intersections. Also, to make comparison between the operational performance of the current situation and the proposed unconventional solutions. In this study signal timing optimization was used as an initial solution before doing any modification on the geometric design. Then, testing the effect of implementing some types of UAIDs including single quadrant, jug-handle, bowtie and Continuous Green T-Intersection (CGTI) as suggested solutions for three highly congested urban arterial intersections in Amman, Jordan. By using microscopic simulation software, Synchro studio 9 with Sim Traffic and using a real traffic data for each intersection. For the purpose of this study the selected intersections were two of four-legged intersection type; Alaqsa Intersection and Ebad Alrahman Intersection and one of three-legged intersection type; Abu Hdeeb Intersection where all of them are complicated intersections. The analysis revealed that the proposed UAIDs succeeded in improving the current intersections where the Level of Service (LOS) improved to be C using Single Quadrant and B using Jug-handle at Alaqsa Intersection, LOS B using Bow-tie at Ebad Alrahman Intersection and LOS D using Continuous Green T-intersection at Abu Hdeeb Intersection.
